The hanging of calligraphy and painting should avoid light. Because the ultraviolet rays in the sun will deteriorate, yellow, fade and brittle the fibers of paper and silk, which is very easy to cause damage to calligraphy and painting, thus shortening the life of calligraphy and painting. In addition, the light emitted by incandescent bulbs and fluorescent tubes also has a small amount of ultraviolet light. Although the impact is not significant, long-term close exposure will also make the calligraphy and painting paper yellow. Therefore, incandescent lamps, fluorescent lamps and paintings should be kept at a distance of more than two meters, and low-power light sources must be selected. It should also be noted that you should use a ponytail broom or cotton dust brush to gently brush the picture every day. Do not use force to avoid stabbing the core of the picture. Also, do not open all the windows to avoid the wind blowing directly into the picture. A small table must be placed in front of the hanging calligraphy and painting to protect it; Don't put anything blocking the painting before the desk, only put incense burner, piano, inkstone, etc.

人们通过收藏，可以丰富审美情趣，提高艺术修养。工余之暇，或河滩沙矿觅石，或乡村小镇淘金；或去古玩地摊寻宝，或到博物馆里取经。流连于蓝天白云下，徜徉在艺术的里，身心得到的放松。对此，古陶瓷收藏鉴赏家马未都先生感触颇深

Through collection, people can enrich their aesthetic taste and improve their artistic accomplishment. In their spare time, they may search for stones in sand mines on the river bank, or seek gold in rural towns; Or go to the antique stall to seek treasures, or go to the museum to get scriptures. Wandering under the blue sky and white clouds, wandering in the palace of art, the body and mind get the greatest relaxation. In this regard, Mr. Ma Weidu, a connoisseur of ancient ceramics collection, is deeply touched

会使你变得谦和待人，荣辱不惊，富贵不淫”。“收藏的乐趣是陶冶，收藏像点燃一支香，望着它永无重复的渺渺烟云，嗅着融和着自然气息的清香，像一杯清茶，在恬静地品啜着，身心得到的松弛和安逸。”收藏界崇尚的思想境界叫“禅”，恐怕指的就是这些。

It will make you become modest and treat others, without fear of honor or disgrace, and without lust. ". "The pleasure of collection is to cultivate. Collection is like lighting a incense, looking at its endless misty cloud, smelling the fragrance that blends with the natural flavor, like a cup of green tea, sipping in a quiet place, and getting the greatest relaxation and comfort in body and mind." The highest level of thought advocated by the collection community is called "Zen", which I'm afraid refers to these.
